wm8960挂载在I2C2上匹配不了驱动这是为什么

我用的是IMX6Q+linux4.1.15内核版本，在设备树文件imx6qdl-sabresd.dtsi 中做修改， wm8960挂载在I2C1上工作正常，挂载在I2C2上匹配不了驱动,wm8960.c中probe未执行，请帮忙分析下原因，谢谢

检查一下使用的i2c2的引脚是否有其他复用，是否有其他驱动

你好，我们现在单独在I2C1上挂载WM8960可以正常工作，单独在I2C2上挂载WM8960也可以工作。但是如果在设备树同时添加两路WM8960的话，两路声卡均不能工作了，打印的log如下，还请帮忙分析下原因，谢谢。

我们硬件威廉希尔官方网站上做了两路WM8960分别挂载了I2C1和I2C2上。刚才已经试过设备树中设置不同的model，名字不冲突了，但是看log中依然找不到audio-routing = 中的一些东西。以下是两路声卡的设备树以及打印的log

目前WM8960输出一路用在耳机另一路用在音响，您看看是不是您设置两路声卡设置的不对，有冲突
